DUMPING-CAR.

SPECIFICATION forming part of Letters Patent No. 236,121, dated December28, 1880. Application filed July 9, 1880. (No model.)

. To all whom t may concern:

Be it 'known that I, MATTHEW VAN Won- MER, of Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Dumping-Cars; and I do hereby declare the following tobe a full, clear, and exact description of the same.

My invention relates to an improvement in that class of railway-carsknown as dumping-ears, which are capable of being tilted sidewise ontheir trucks to empty their loads in bulli.

The novelty ofthe invention consists in the construction and combinationof the devices employed, as will be herewith set vforth and specificallyclaimed.

In the accompanying drawings, Figure 1 is a side elevation of myimproved dumping-car. Fig. 2 is an end view of the same. Fig. 3 is aplan view. of the body taken oftI the trucks and inverted. Fig. tisasectional end view through the line a; x of Fig. l. Fig. 5 is asectional side elevation through the line y y of Fig. 2.

Corresponding letters of reference refer to like parts in all thefigures.

The trucks A may be of the usual or any suitable construction.

Upon the top of each upper truck-timber,

at its middle, is secured the center body-bean.

lng plate, B. (Shown at Fig. 6 in perspective.) This plate is concave,as represented, and has a central frusto-conoidal boss or extension, a.,

through which the king-bolt passes down into the truck-timber and servesto lock the plate B thereto. The head of the king-bolt b is shapedA tocomplete the cone of which the boss upon the plate is a frustum, as seenin Fig, 6. These plates B and their king-bolts form eenter bearings forthe body of the car. Upon each side of the plate B at metal plates O aresecured to the upper truck-timber, and through each is one or moreapertures, form,- ing recesses c, whose office will he hereinafterexplained.

Bolted to the side of each upper truck-timber, in any suitable manner,is a segmental rack, D, with the concave side uppermost, as Shown.

The platformor bed of my improved car body is composed, essentially, ofthe side beams, E, end beams, F, longitudinal central beams, G, andtransverse central transoms or beams, H, supported by the beams Gr.

Directly over each truck-timber is a rockerpiece, I, hat on top andconvex on its under surface, the whole forming the segment of anellipse, as represented. These rocker-pieces may be of wood, with thebeams G mortised through them, and they are further supported by metalstraps or plates J and K, of which the former passes over and the latterunder the rockers I, and have their outer ends, which are turned down,bolted to the side timbers, E. While the under surfaces of the plate Kare convex to conform to the rockers I, their outer ends are concave, asrepresented, for a purpose to be hereinafter explained. To strengthenand stiften this frame-work I employ the girder-rodsf, as represented,and to form a further support for the bed-planks I use metal straps L inpairs, which are bolted to the end timbers, F, as represented, pass overthe plates J and'K and over and under supporting-blocks secured upon thetransverse beams H.

Securely bolted or otherwise fastened to the lower side of the rockers Iat their middle are center bearing -plates, M, with convex lowersurfaces, and having in each 'a central recess or aperture, g, toreceive and contain the heads of the king-bolts and the frusto-conoidalstem of the plates B. It is thus clearly seen that the body of the car,by the intervention of the plates M, rests upon the plates B as centralbearings, and at the same time the king-bolts and the stems of theplates B form pivots for each of the trucks while turning curves.

To dump the car to either side I employ a central longitudinal shaft, N,which is journaled in hangers h supported by the beams G, and is furthersupported by passing through openings in the rockers I and beams H. Thisshaft carries two pinions,O,keyed toit, which engage respectively witheach of the racks D. The teeth of the pinions are tapered at each side,so as to permit of the play between the parts requisite in turningcurves. Keyed upon the end of the shaft N, just under the platform atone end of the car, is a worm-wheel, P, which engages with a worm, It,secured upon a vertical shaft, S, passing up through the platform, andprovided with a crank or hand wheel, T. By turning said hand-wheel theshaft N is caused to rotate and the car is tilted to either sidedesired. By the employlnent of this dumping-gear with a worm-shaft apositive lock is always secured, no ma-tterin what position the body ofthe car may be. It cannot movefrom that position withoutabrealc age ofsome of the parts. To assist, however, in retaining the car in anupright position and lessen the strain upon the dumping-gear, I employrests or side beams, U, which consist of cylindrical metal piecescarrying pivoted friction-rollers i in their lower ends, as seen. Thesesupports, Fig. 7, are recessed in metal sockets secured in the rockers Ion each side of the center bearings, and are provided withlaterally-projecting pins j, which, traveling in slots in the sockets,prevent the supports from falling out of said sockets, and furtherprevent them from turning therein. These supports are sufficiently long,also, that when dropped down to their lowest extent their rollers irestupon the plates C. To lock them in this position so as to enablethem to support the body of the car on each side, I employ rods 7c,having their forward ends connected to levers W, which, pivoted belowthe platform, pass up through openings in the same. Each of these rods7:, which are supported in the sockets I so as to slide therein, isprovided with two slides, l, of the shape represented, and so {ittedinto transverse openings in the rockers I, adjacent to thesupport-sockets, that when said rods are shifted by their levers theslides l. will pass over the tops of the supports and prevent them fromascending into their sockets.

When it is desired to dump the car it is only necessary to unlock thesupports on the dumping side ofthe car, when, byturning the halidwheelas aforesaid,the car will turn and empty itself. During this tiltingofthe car the supports or side bearings which were unlocked will bepressed up into their sockets, out of the way, and will not interferewith the dumping. Vhen the car, after being dumped, is tui'ned back to ahorizontal position the supports will fall of their own gravity back totheir former position, when they can be locked as aforesaid.

In order to prevent the ear while in the act of being dumped from beingdisengaged from its center bearings, I employ studs or dowels on, whichare secured in any manner desired to the under side of the rocker-platesK, between th'e supports U and the center bearings. These dowels,whilethe caris tilting,enter the apertures c in the plates B and serve toprevent the car from slipping or heilig displaced. The apertures c, asseen, are suiliciently wide to receive the dowels, even though the carwhen being dumped stood on a short curve.

Especial attention is called to the Hoorplanks X, which are raised, asseen, just over the rockers, for the purpose of enabling the car ,to betilted over farther without raising the bed higher than other cars ofthis class, or of ordinary cars. This result is further contributed toby the curved portion p of the rocker-plates-K, and bythe employment ofthe strap-supports L, which,lying upon each other, occupy very littlespace.

The sides of the car are movable gates A', which are held in slottedposts or supports B, and these posts form journals for shafts G', asseen. The gates A', of which I employ two or moi'e on a side. which arefree to slide up and down in the slots of the posts, are connected tothe shaft C by chains, ropes, or wire cords D. as shown.

By employing permanent or removable cranks at either end of the shafts Cthey may be rotated, thus winding up the chains D and causing the gateson either side to be raised simultaneously. A reverse motion wouldpermit them to fall by their own gravity.

Another valuable feature of my invention consists of a director-boardfor causing the dumped inaterial--as gravel, for instance-to fall closeto the rails ofthe track. This I accomplish by hinging` a board, E', tothe side beams by means ot' pivoted bracket-arms F', arranged as shown.By means ot' these swinging arms the board, when not wanted for use, canbe swung around so as to lie close to lthe side ofthe car, in whichposition the contents of the car would pass over it while heilig dumped;or it can be swung out, as shown in Fig. 4, when it could act as adirector to throw the load of the car close to the rails.

It will be observed that the dowels upon the under side of the rockercould be transferred to the plates C, and in that case the recessescwould be formed in the plate K ofthe rocker.

Having thus fully described my invention, what I claim is- 1. In adumping-car, the combination of the followinginstrumentalities:segment-racks attached to the trucks, pinions engaging with said racks,attached to the car-body by a common shaft, and an actuating worin-shaftconnected to the pinion-shaft by a worin-wheel, whereby the car can bedumped to either side, and whereby a positive lock is eected between thecar body and trucks, no matter in what position of inclination thecar-body may stand.

2. In a dumping-car, the combination, with rockers upon which thecar-body turns and rests, of central bearing-pivots consisting ofconcave plates B, with frusto-conoidal stems, and king-bolts whose headscomplete the cones of which the plate-stems are frustums, as specified.

3. In a dumping-car, the combination, with the trucks, whose uppertimbers are provided with central bearings and pivots and flat metalbearing-plates, of convex rockers at- IOO IIO

tached to the body of the car and mounted upon said central pivots andbearing-plates, as specified.

4. In a dumping-car, the rockers I, carrying upon their under surfacesthe reversed curved metal plates K and the central recessed convexbearing-plates M, in combination with the subjacent concave plates B andtheir conical pivots, substantially as specified.

5. In a dumping-car, the combination, with rockers upon which the bodyturns and rests and by which it is pivoted to the trucks, of telescopicgravitatin g side bearings, whereby, when said side bearings areextended and locked, tbe car-body is prevented from turning to eitherside, as speciiied.

6. In a dumping-car, the combination, with the rockers I, ot the sidebearings or supports, U, recessed in sockets in said rockers andcarrying at their lower ends friction-rollers, as and for the purposespecified.

7. In a dumping-car, the combination, with the telescopic gravitatingside bearings or supports, U, of locking-slides connected to shiftingrods actuated by levers upon the platform, whereby, upon moving saidlevers in one direction, said side bearings are locked to enable them tosupport the body of the car and prevent it from tilting, and whereby,upon moving said levers in an opposite direction, said side bearings areunlocked and will permit the car to be dumped by ascending into theirsockets, as specited.

S. In a dumping-car, the combination, with the rockers I and recessedplates C, of dowels or studsconnected to the lower side of said rockersand adapted to enter the recesses in the plates to prevent the body ofthe car from slipping or becoming displaced when dumped, as specied.

9. The herein-described construction ot' the car bed or body, consistingofthe side beams, E, end beams, F, longitudinal central beams, Gr,transverse central transoms, H, girder-rods f, and strap-braces L, thewhole constructed and united in the manner and for the purpose specied.

10. The vertically rising and lowering gates A', in combination withactuating-shafts C', connected thereto by chains, ropes, or cords, asspeciiied, whereby upon rotating said shafts the gates on either sideare raised or lowered simultaneously.

1l. In a dumping-car, the bed or platform raised transversely across andabove the trucks, whereby the car can be turned over farther withoutraising the main body of the car higher than ordinary cars,substantially as described.

12. In a dumping-car, the directing or delecting board, hinged to theside of the car by swinging brackets, substantially as shown anddescribed.

In testimony whereof I have hereunto set my hand.
